Hemorrhoidal dearterialization with mucopexy versus hemorrhoidectomy: 3-year follow-up assessment of a randomized controlled trial.

ABSTRACT

BACKGROUND: A randomized controlled trial showed that patients with grade III or IV internal hemorrhoids had similar symptomatic relief of symptoms up to 3 months following dearterialization with mucopexy or hemorrhoidectomy albeit with less postoperative pain after the former. This study aimed to compare hemorrhoidal recurrence and chronic complications at 3-year follow-up. METHODS: This study was carried out on 40 patients with grade III or IV internal hemorrhoids previously enrolled to a randomized trial comparing dearterialization to hemorrhoidectomy. Recurrence was defined as internal hemorrhoids diagnosed on proctoscopy. Chronic complications were nonresolving adverse events related to surgery. Outcome measures included patient-reported outcomes and quality of life measured by brief pain inventory (BPI), SF-12, and fecal incontinence surveys. RESULTS: At median follow-up of 36 (27-43) months, 13 patients (32.5 %) were lost to follow-up. Patient-reported outcomes suggested no difference between dearterialization and hemorrhoidectomy in persistent symptoms, occurring in 1 (8.3 %) vs. 2 (13.3 %) patients (p = 0.681) and in symptom recurrence, occurring in 6 (50 %) vs. 4 (26.7 %) patients (p = 0.212). On proctoscopy, recurrence was seen in 2 (13.3 %) vs. 1 (6.7 %) patients (p = 0.411), all with index grade IV disease. One patient in each arm required reoperation (p = 0.869). Chronic complications were not seen in the dearterialization arm while they occurred in 2 (13.3 %) hemorrhoidectomy patients (p = 0.189) and included unhealed wound (n = 1), anal fissure (n = 1) and fecal incontinence (n = 1). There was a trend toward more patient reported than actual recurrence on proctoscopy (10 vs. 3, p = 0.259). There was no difference in BPI, SF-12, and fecal incontinence quality of life scores. CONCLUSIONS: Recurrence rates did not differ significantly at 3-year follow-up and occurred in patients with index grade IV hemorrhoids. Chronic complications occurred only after hemorrhoidectomy.
